Advertise it in your local paper and get the person who buys it to take it down and remove.

Or join your local 'Freecycle' group if you feel generous, and want to give it away. You can still say that the person who wants it will have to dismantle it and remove it!

Metal frame or wooden?

moon grower is right but if you get know joy i would jently take it apart from the very top down a layer at a time as the glass especialy if its a wooden frame could be the only thing giving it any integraty .if you cant take it apart in one piece then get some old blankets and completly cover it . then when you break it up the glass will stay safe .
